Regardless of the criticism, William said he didn't think the show was too crass or crude: "Everyone’s like, ‘the show is full of sex and violence and bad language’ and I’m like, ‘have you seen Game of Thrones?’ They have orgies every episode. People get their heads cut off every episode and that’s what people tune in for. It sells.

"Ours is a very mild version of that. I think where people get a little bit uptight is because it’s the Royal Family. They’re doing drugs, having sex and having wild times. But we all know they do that anyway. Everyone’s seen the pictures of Prince Harry out in Vegas. Life is life. Enjoy it."

The 29-year-old revealed that despite the explicit nature of scenes, he doesn't really prepare for them: "I just enjoy them [laughs]. I just get in there and have a great time and then I leave.

WILD CHILD: William doesn't prepare for the scandalous scenes of The Royals

"The emotional ones I prepare for because you cannot show up where I have to break down in tears, shout and be in an angry head space if I haven’t got myself ready beforehand. That takes a lot of your energy."

Filming for series three of The Royals commenced in London last week and William hinted at what's in store for Prince Liam: "I’m more excited for this season than I have been for any of the others because he’s free, he’s open, he can do whatever he wants and it will be fine.

"I think if he wants to fight someone he can fight them. If he wants to get drunk he can get drunk. If he wants to go off with this girl, that girl, he can do whatever he wants."
